But that's not important....

What is important is that they are (and, I suspect, always have been)
*out of phase* with each other!! And no, before you ask, there's no way
I got the I/P signal wire twisted up!!

If their new owner disagrees with me I will post a retraction (or say

them in phase...??

One of the many benefits of overall negative feedback in a valve amp is
that it ensures you get the output transformer phased right. With no
overall NF on these amps, they will work equally well either way round.
There's no excuse for sloppy manufacture, but at least with NF, it would
never have left the factory like that. (assuming of course that they
were tested at all)

OK Serge, where is this going to have happened then?

I'm certain I haven't buggered up the coax signal wires but I'm equally
certain they amps are out of phase, is it likely to be the transformers?
Doesn't help the amps are handed but the speaker connectors are colour
coded red/black/red, so it's not a question of how they are hooked up!

Since valves are basically unbalanced devices, the problem must be in the
output transformer?

Just had a thought. You have an out of phase transformer in this amp,
and another one in your Oktava mic. Put the two together and
everything is well again.

Wakey wakey, Donald - they ain't my amps! But yes, I do still have a

I returned the amps earlier this evening - it's the new owners problem

This isn't something that has changed, they must have been like that
from new. There's no mechanism that will change the phase. Nick's
suggestion is correct, compare the connections in and out of the output
transformer, and see if they are different. It could be that the
transformer connections are identically colour-coded but that the
transformer itself has been wired differently. If so, just reverse the
b+ and 300b anode connections on one amplifier. I suppose you should
find out which amp is out of phase, and reverse the other one, but
unless the new owner is one of these "absolute phase" nuts, it doesn't
matter provided they are both equally phased.

No, I didn't expect there would be and it's a certainty the first owner

As I said earlier (?), they are no longer here. Whether or not the
present owner will want anything done about it (or even agrees) remains
to be seen.

I will talk to you in the next day or to about it, but can you tell me

Anyway, it looks like they *are* out of phase and I was informed in a
subsequent phone conversation that this guy's work colleague (where the
TLS80s came from) had apparently said he thought they sounded 'vague'

Not so. But a technology which hasn't been developed since the '30s is
indeed a dead one. Plenty of things are similar in principle but developed
to greater heights. The obvious one being the internal combustion engine.
Even your favourite Lowthers have changed substantially throughout the

The 5V heater is a clue to the fact that it was to designed to be used
with its cathode up at HT volts, where it could safely share a heater
supply with the rectifier. If it had been designed as an output valve,
it would certainly have been given a 6.3V heater.

Well, no its not Dave, if the goal that Keith is looking for was the
same goal that the designers were working towards in the 30's, and after
that date the goal changed, then there is no reason for the 30's product
to not be the best there is, given Keith's set of prioritys.

It may not be what _you_ call perfection, but thats a different thing
altogether.

FWIW, there has been some development on the 300b design in the last 15
years or so, the KR300bXLS (for example) is a development of the
original design, and its very different internally. Of course the pace
of development and the financial support is lower than it is for other
areas of electronics, but the fact that there is development must be the
result of the existance of the market for such devices over the last 20
years or so.

Likewise, the Chinese metal plate version of the 845 shows that there is
still work being done. It may not make it mainstream, but it does make
it far from obsolete (if only by your own definition above).

Interesting theory, I agree its not a battery valve, hence it not having
a 6.3v heater, but then if you look at US mains valves before the second
world war, many have 2.5v multiple heaters, 2a3, 45 (2.5v), 211, 845 (10v).

It was a good theory, but it was only after the war (world,2nd) that 6.3
became a standard voltage for many valves low power valves, not just the
ones designed for battery sets. Then again the P series was possibly
even more common esp in television sets.

Install Vista on a laptop? I expect I'd manage.

Or did you mean something else? If you mean valves and vinyl - yes I can
listen to both. Although not at the same time - I'll leave you to work out
why if you can.

indeed a dead one. Plenty of things are similar in principle but
developed
to greater heights. The obvious one being the internal combustion
engine.
Even your favourite Lowthers have changed substantially throughout
the
years. So the idea of a '30s valve being 'perfection' is sheer
nonsense.


Well, no its not Dave, if the goal that Keith is looking for was the
same goal that the designers were working towards in the 30's, and
after that date the goal changed, then there is no reason for the 30's
product to not be the best there is, given Keith's set of prioritys.

It may not be what _you_ call perfection, but thats a different thing
altogether.


I don't think Plowie's idea of perfection would be of the least interest
to me. Last night I listened to *4 sides* of Finzi's 'Earth And Air And
Rain' song cycles (vinyl/SET/horns, naturally) and I doubt he has *ever*
heard the like - or he wouldn't make some of the silly remarks that he
unfailingly does, sooner or later....

I have had to laugh...

I suspect you are unable to do that...??

Install Vista on a laptop? I expect I'd manage.

Or did you mean something else? If you mean valves and vinyl - yes I
can
listen to both. Although not at the same time - I'll leave you to work
out
why if you can.


When I see this sort of reply from you I am always reminded of this:

A: A weasel is weasily recognised, while a stoat is stoatally
different....

Just thinking out loud. I don't know the history of that valve.

It was a good theory, but it was only after the war (world,2nd) that 6.3
became a standard voltage for many valves low power valves, not just the
ones designed for battery sets. Then again the P series was possibly
even more common esp in television sets.


It was designed for series connected heater the current through each
valve being the same. They were all connected thus with the exception
of the EHT rectifier, which had its own winding on the line transformer
and a dropper resistor was then added in series to take up or drop the
excess voltage.

Some sets used a wattless dropper i.e. a capacitor for that function....

Keith, I also might not *ever* have heard the like, but would I find it
a pleasant experience? vinyl/SET/horns are not my preferred system.

OK, this my first post from the new machine!

No, you would hate it!!

I know....

So I would turn the volume on the SET down and press a button on the SS amp
and you could have it over the TL80s - takes 5 seconds.....

Then, I suspect you would *love* it!! :-)

I expect I have heard 'the like' - about 40 years ago. But things have
moved on since then in audio reproduction. Including your ears, sadly.

Moved on? How exactly?

Mahler/Beeth/Brahms/Schubert/Frank Zappa are somehow *different* these
days??

These are 'audio reproduction' are they?

It's called a tag line. A sig is a signature. Just for accuracy - the
